National Instruments headquartered in Austin offers SystemLink, a software platform for managing system configurationt tasks, device management, software deployment, to improve system uptime and performance.
1. It's open source which supports range of languages, operating systems and languages. Well suited for Android and IOS mobile automation. Supports all kinds of apps, which makes it flexible and robust mobile testing tool 2. It is less appropriate where we need intercept network call to verify the API calls. Extensive coding experience is required to work Appium
There are definitely scenarios where NI SystemLink will be useful but just didn't work out well for us. I needed to be able to replace an EXE file on a computer with a new EXE to do the upgrades but I was not able to do that through SystemLink. You had to work with packages in order to perform this and I didn't want to revamp my distribution plan. We also didn't need to do any asset management or calibration documentation through SystemLink. I was excited about being able to view data from the test stations through a browser but our engineers need historical data available and everything resets to a live view when you click back to the UI.
I would like to give 9/10 rating to Appium because of it can easily integrate with popular frameworks and CI/CD tools, as well as it is reliable, flexible and easy to use. The setup can bit complex in initial step, but once on configured it's very easy to use and enables stable and scalable mobile automation for real and cloud devices.
If you're an Apple developer, you use Xcode. It's practically a forced necessity. For system testing though, it doesn't have to be. You can have your development team focus on unit and integration tests in their platform and another team automate acceptance tests with a language they are more familiar with.
